In the old days, if a person with a TS/SCI clearance left a briefcase in a bar everyday for years, had an affair or a nap or whatever in the back room, then returned and picked up the briefcase, that person, when caught, would not be able to claim they had no idea that the briefcase might have been compromised by foreign intel. services.
What Hillary did was far worse. She left TS/SCI/SAP documents open for anybody to read.
I assume that the Russians, Chinese and Iranians are now in a position to blackmail her. The FBI might not have been able to recover 30K deleted emails, but our enemies were reading (and saving) them in real time.
I don't think it is possible to shame or blackmail any Clinton. They could be the envy of the political class world-wide.
